Good Boy Vodka Seltzers (assorted Flavors) Recipe

Make chilled vodka-syrup base

In a large mixing pitcher or bowl, combine 1 cup vodka, 1/2 cup chilled simple syrup, and 2 tablespoons fresh lime juice. Stir to combine. Keep chilled in the refrigerator while you prepare flavor concentrates.

Measure and chill 2 cups plain seltzer in the refrigerator so it's very cold when assembling. Cold seltzer preserves carbonation when mixing.

Raspberry concentrate

If using fresh raspberries, macerate 1/2 cup raspberries with 1 teaspoon simple syrup, then press through a fine mesh strainer to yield about 1/3–1/2 cup strained purée. Optionally add a few drops berry extract or 1/4 tsp citric acid to brighten. Keep chilled.

Grapefruit concentrate

Strain fresh grapefruit juice to remove pulp until you have 1/2 cup. If desired, add 1/4 teaspoon simple syrup or a tiny pinch of citric acid to balance bitterness. Chill.

Peach concentrate

Peel and pit ripe peaches, blend until smooth and press through a strainer to collect 1/2 cup purée. Add 1/2 teaspoon simple syrup if fruit is underripe. Chill.

Cucumber concentrate

Peel and core 1 medium cucumber, blend and strain to get 1/2 cup green cucumber juice. Optionally mix in 1/4 teaspoon lime juice and a pinch of salt for balance. Chill.

Each finished can is approximately 12 oz (360 ml). For four cans you will scale accordingly. Work one can at a time to preserve carbonation.

Measure flavor and base

For each 12-oz can, use roughly 1.5 tablespoons (22 ml) flavor concentrate, 3 tablespoons (45 ml) vodka-syrup base, and fill the rest with chilled seltzer (about 9–9.5 oz / 270–285 ml). These proportions yield around 4.5% ABV and a balanced flavored seltzer. Adjust flavor quantity 1 tablespoon up or down to taste.

Combine gently

In a chilled mixing glass or directly into the chilled can/bottle, add the measured flavor concentrate, then the vodka-syrup base. Top slowly with chilled seltzer to preserve fizz; do not over-stir. Gently roll the can between your hands or stir once with a bar spoon (no vigorous shaking) to combine without losing carbonation.

Taste and adjust

Taste one sample. If too sweet, add a splash more seltzer. If too weak in flavor, add up to 1 teaspoon extra flavor concentrate. If brightness is lacking, add a few drops of fresh lime or 1/8 tsp citric acid and stir gently.

Package & garnish

Pour into chilled cans or bottles, leaving ~1/2 inch headspace. Add garnish as desired: 3–4 raspberries for raspberry cans, a thin grapefruit wheel for grapefruit cans, a peach slice for peach cans, or a cucumber ribbon tucked inside for cucumber cans. Seal cans or cap bottles immediately and keep refrigerated.

Store finished seltzers chilled and consume within 3–5 days for best flavor and carbonation. Gently invert or roll before serving if settling occurs; avoid shaking. Serve ice-cold.

Estimated carbonation and flavor may vary by seltzer brand; taste and adjust the concentrate ratios the first time you make each flavor so you can replicate preferred levels next batch.
